And based above you can see that “v11.0” LocalDB instance is Windows Azure Storage Emulator specific. When DSInit starts first time it creates the v11.0 database in LocalDB. You can verify it as below:

c:\>sqllocaldb iv11.0

If you want to choose Local SQL Express DB instead of LocalDB, you would need to change the <SQLInstance>**</SQLInstance> property to add proper Database name.
